Precision Pneumatic Flow Controls

Fine Pneumatic Speed Adjustment in a Compact Flow Control

NASC precision flow controls are lightweight and compact, making them suitable for fine adjustment of pneumatic actuator speed. An included lock nut allows panel-mount installation where a stable adjustment point is required.

The flow control provides one-way restriction with freer flow in the opposite direction. It is commonly used to meter exhaust from pneumatic cylinders for smoother extension or retraction.
